FBANKS. HYATT, OF BROOKLYN, NEW'YORKZ CLOSURE FQR CONTAINERS;

Application filcd a pri-l 6,

This invent on relates .tothe constru t n oi powder containers and is particularly adaptedforuse when it is desired to use a container body oi: nonarnetallic material, such as glass." The inventionparticularly relates to the manner ofs'ecuring-thesitter topa nd closure to the bbdy of the container. 'Theobje'ct of "theinvention is to improve the mahnerarid meansof"sfecnirin'g the top and-cap to'themontainer r The invention" consists? in the improved powder container hereinafter more particu larly describedandthen specified inthe claims- In the accompanying drawings: Fig? 1' is a front elevation of a powder container embodyiIIg theinvention; U

Fig. 2 is a side elevatibn of the same, the cap; being-removed. a. I

Fig. 3is an enlarged vertical cross-section through the neck portion oi th'e'container. Fig. 4: is a plan viewofi the sitter top. The inventionisparticularly useful as a means for quickly and efliciently attaching a sitter top and cap to a glass powder container body and it will be described as applied to this use without, however, in any manner limiting it thereto except as may be expressed in the appended claims.

In the drawings, 1 indicates a body preferably of glass and adapted to contain and dispense such material as talcum powder. 2 indicates the neck thereof, cast or formed integral with the body 1. The neck also has screw threads preferably in the form of inclined projections 3 cast or otherwise formed on the exterior of the neck. A bead at is also cast or formed about the periphery of the neck 2 at the outlet end of the neck and above the portion having the screw threads, the outside diameter of said bead being as shown somewhat less than the extreme diameter of the threads or threaded portion. 5 indicates a sitter top preferably of sheet metal which closes the opening in the neck 2 and is provided with discharge or sitter 1920.

openings 6. The top. 5 is priovide'd witha downwardly projecting, inwardly. curved the bead 4 andcurve under and grip the .under side of the bead, The flange 7 is prefers ably provided. withia number of slits 8 run ning inwardly from the free edge'ofthe flange. providing theselslitsthefflange can be readily sprung over 'tlrejbeadja Whereby'the top.'5 maybe secured ito the 'necksby hand. 1 c Y The bead 4 is; as shown, made so small as to its extreme outside diameter that after the flange is applied the extr'erne diameter including, themetal flange is lessthanthe smallest internal diameter j oft-he cap 9 01* portion thereof "whichehgage's the neck below the" head for the purpose Tof securing said capin'placeso as to close and sealthe openings in the top- 5 when thecontainer is not in'use. This cap" is ofmetal and is pref erably cup-shaped and provided withsc'rew threads 10 adapted to engage 1 the inclined projections or screw threads Bbnthe neck 21 By rotatingthe cap-in the properdirection it seats on the topo-andfcloses the. openings therein, a compressiblepad I1being provided betwcen the cap 'and top. While said pad 11; might'be omitted,it ispreferable' to employ the same because it not only actsito thoroughly seal the ='perforate'd p'or-tion and prevent accumulation of powder within the cap but it also acts, after the manner of a spring lock washer, to prevent the loosening of the metal screw top or cap upon the threaded portion of the glass top.

From the foregoing it will be understood that the cap 9 envelopes the sifter top 5 in such a manner as to prevent any leakage occurring, it being noted that this result is achieved incident to the fact that the inner surface of the cap 9, as well as the pad 11 which may be carried thereby, are preferably concaved, while the co-operating perforat'ed surface of the sifter top 5 is convex. Thus upon these parts being drawn into intimate Contact with each other incident to the action of the screw threads or other means utilized to accomplish this purpose, it

will beobvious that a seal is provided which renders an escape of the contents of the receptacle impossible. Also due to the fact that the head 4: with the sifter top applied,

is of less diameter than the threadedporstood that the cap may readily be applied and removed rom the neck.

hat I claim as my invention ISI- 1. A receptacle having a neck, a sifter top presenting a perforated body, said top be-' mg secured to said neck adjacent the outer end of the same, a removable imperforate cap having its inner face conforming to the entire outer perforated surface of said top and means on the neck below the edge of the sifter top for drawing said cap into intimate contact with said outer face of the top.

2. In combination, a receptacle formed P with a neck, a sifter top presenting a perforated body, said top being secured to said neck and positioned at the outer end of the same, a removable cup-shaped imperforate cap having its inner face conforming to the entire outer perforated face of said top, and screw threads provided on both said neck below the edge of the top and side walls of said cap, whereby upon said threads being operatively engaged, said cap may be drawn into intimate contact with said sifter top.

3. A receptacle having a neck forming a part of the receptacle, a bead formedadjacent the end of the neck and on the outer face thereof, and screw threads forming a part of the neck and below the said bead, the base of the screw threads having a diameter greater than the diameter of the bead.

4. A receptacle having a neck forming a part of the receptacle, a. bead formed adjacent the end of the neck and on the outer face thereof, and screw threads forming a part of the neck and below the said head, theportions of the screw threadshaving a diameter gre-ater'thanthe diameter of the bead.

5. A receptacle having a neck forming a part of the receptacle, a bead formed adjacent the end of the neck and on the outer face thereof, screw threads forming a part of the neck and below the said bead, the: screw threads having a diameter greater than the diameter of the head, said head presenting a shoulder portion, combined with a sifter top applied to the end of the neck and having portions of its body bent to engage said shoulder, and a cup-shaped cap bearing against the outer face of said top, the side walls of said cap being formed with interior screw threads adapted to engage the screw threads of the neck;

6. A receptacle having a neck forming a part of the receptacle, a bead formedadjacent the end of the neck and on theouter face thereof, screw threads forming a part of the neck below said head, the screw threads having a diameter greater than the diameter of the head, said head presenting a shoulder portion combined with a sifter top applied to the end of the neck and having portions of its body bent to engage said shoulder, and a cup-shaped, cap bearing against the outer face of said top and over the entire perforated surface thereof, the side wall of said cap being formed with in-- terior screwthreads adapted to engage the a screw threads of'the neck whereby the inner face of said cap, and the outer face of said top may be forced into intimate contact with each other.
